The SMBJ8.0A with TVS SMB (DO-214AA) RoHS manufactured by Yageo is an axial leaded, surface mount, unidirectional device designed for transient voltage suppression in low-power applications. It can be used for the protection of data lines (RS-485, USB, CAN bus, I2C, etc.) from electrical overstress caused by lightning and other sources. This particular device is a Transient Voltage Suppression diode that can dissipate up to 8.0 Amperes in peak pulse currents. It offers a wide operating temperature range of -55°C to 150°C, with peak pulse power dissipation of up to 321 Watts. Furthermore, this device is rated for a breakdown voltage of 8 Volts and has a working peak reverse voltage of 6.4 Volts. This device is RoHS (Restriction of Hazardous Substances) Compliant and meets all environmental standards set forth by the European Union.
